They've recently sparked rumours of a romance after getting close whilst filming their latest project in France.

And while Tom Cruise has starred opposite some of Hollywood's most beautiful women (including ex-wife Nicole Kidman), it seems his latest leading lady is a dead-ringer for one of his most famous.

Believed to be the latest femme fatal in the on-going Mission Impossible series, Vanessa Kirby's look for the film may have given passers-by cause to do a double take as she filmed a kiss with Tom - as The Crown star bares more than a passing resemblance to Top Gun's Charlie.

The flight instructor, whom Tom's character falls for in the 1986 film was played by Kelly McGillis, and with her curly blonde locks falling around her striking features.

Rocking retro look, thanks to her long white belted raincoat and knee-high brown boots, Vanessa's unknown character appears to have a penchant for the retro look.

Having ditched her brunette colour that she sported in Netflix's royal drama to play princess Maragaret, the British-born actress has now gone bleach blonde.

Her likeness to Kelly was very noticeable on Tuesday, when she and Tom were seen on the (as of yet) unnamed Mission Impossible title.

Hollywood megastar Tom, 54, was looking dapper as he filmed a romantic scene with pretty co-star, 29, on the set of the action movie in Paris.

Tom and Vanessa were seen locking lips for the cameras and chatting and laughing between takes, while Tom also gave a wave to spectators watching the action.

Tom, who reprises the role of Ethan Hunt, was dressed in a sharp, while Vanessa – best known for her part as Princess Margaret in Netflix’s The Crown - looked glamorous in a sleek white coat and over the knee brown boots.

The co-stars were romantically linked back in March after US magazine In Touch Weekly claimed sparks flew when they met each other on the Mission Impossible 6 set.

Sources close to the actor alleged Cruise had been “blown away by her endless charm and energy” and has not ruled out walking down the aisle for the fourth time.

"Tom flipped for her work," an insider claimed.

"He told the other MI producers that he had to have Vanessa for a crucial role in the franchise's sixth instalment. They had instant chemistry, and of course she got the role.

“He’s blown her away with his endless charm and energy."

However, a source close to Vanessa denied any romance off camera, telling ET Online that such speculation is "not true".

Mission Impossible 6 has been filming in Paris for weeks; Tom and Vanessa co-star alongside Henry Cavill while stars reprising their roles in the franchise include Rebecca Ferguson, Alec Baldwin and Simon Pegg.

Details of the plot have been kept under wraps but director Christopher McQuarrie has teased viewers will see a "very different" side to Cruise's character and possibly more information about Ethan's private life.

"It’s a very different Ethan Hunt, I can promise you that," he told Empire .

“I’ve seen five of these movies and I don’t know who Ethan Hunt is. One movie sort of dealt with his personal life; the other movies are about people speculating what’s really going on in Ethan’s head. I want to know who Ethan is in this movie, I want an emotional journey for this character, and Tom really embraced it.”
